Description

Fixing device for trachea cannula

Technical Field

The utility model relates to a clinical medical instrument technical field, concretely relates to trachea cannula's fixing device.

Background

In clinical medicine, a trachea cannula is often adopted, which is a technology that a special endotracheal tube is placed into a trachea through a glottis, and provides good conditions for treating sudden stop of breathing, airway obstruction, hypoxia or insufficient ventilation and the like. Because the trachea cannula passes through the oral cavity of a patient and has certain flexibility, the trachea cannula is usually used for placing a dental pad between upper and lower incisors of the patient after the success of the trachea cannula is determined in order to avoid the blockage of the trachea cannula caused by the occlusion of teeth of the patient, the trachea cannula and the dental pad are fixed by an adhesive tape, and the trachea cannula is fixed on the cheek part of the patient by the adhesive tape. The fixing mode mainly depends on that the adhesive plaster pulls the skin, so that the patient is easy to feel uncomfortable, and particularly, under the condition of vague consciousness, the patient can easily touch or tear the adhesive plaster by hand based on the conditioned reflex, so that the tracheal cannula is loosened and misplaced; in addition, the adhesive plaster has poor air permeability, which can cause skin allergy of some patients.

Application No.: 201621178414.4 discloses a disposable bite-block for fixing tracheal catheter, application No. 201720423328.3 discloses a bite-block device for preventing tracheal catheter from being broken, which is characterized in that an arc fixing part is connected with one side of a bite-block main body by a connecting part, the tracheal catheter is sleeved in the arc fixing part, although the tracheal catheter and the bite-block are prevented from being connected by adhesive tape, the tracheal catheter and the bite-block still need to be fixed by other modes when in use, so as to prevent the tracheal catheter from moving in the oral cavity. And they all have a common problem, only pay attention to the trachea cannula anti-blocking setting in the oral cavity, in order to neglect when the patient position changes (such as turns over, twists the head or sits halfway), trachea cannula also appears blocking between oral cavity and breathing machine easily.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
